Music fans, prepare to rock. Bonnaroo, the annual four-day festival held on a farm in Manchester, Tenn., has announced its lineup for 2013, and it's not just studded with stars -- it's swarming with them. Among the biggest headliners for this year's event, to be held June 13 through June 16, are Paul McCartney, Tom Petty & the Heartbreakers, Wilco, and Album of the Year Grammy Award winners Mumford & Sons.

Hip hop veterans Wu-Tang Clan will also take the stage, along with R. Kelly, rapper Nas, Bjork, the National, Passion Pit, and the Lumineers, who were nominated for Best New Artist at this year's Grammys. Folk music and country fans can catch a performance by Dwight Yoakam or join The Office star Ed Helms at his Bluegrass Situation Superjam tent.

"Top to bottom, this is one of the strongest lineups we have ever had," Bonnaroo spokesman Jeff Cuellar told Reuters in an interview. "Looking at the festival landscape out there...no other American festival has Mumford & Sons, Paul McCartney, and Bjork all under one roof."

The lineup was announced on Tuesday, Feb. 19, in an hour-long live telecast hosted by Weird Al Yankovic (among this year's festival acts). Bonnaroo performers Portugal. The Man also appeared, to sing "So American."

Bonnaroo is one of the biggest live music festivals in the country, along with the Coachella Valley Music and Arts Festival in Indio, Calif. Up to 100,000 fans -- including many celebrities -- flock to Great Stage Park every year to see their favorite bands and comedians perform.
